Extinguish is an Android utility app developed by Mokarate, available for free on the Google Play Store. This app allows users to turn off their screen while keeping the device awake, enabling other apps to run without the screen going to the lock screen. By leveraging Extinguish, users can achieve various behaviors such as turning off the screen and hanging up, listening to others while taking notes, and watching videos with the screen off. This functionality is especially useful in scenarios where the screen consumes a significant portion of the device's power, potentially leading to screen burn on OLED displays. Extinguish offers a solution to mitigate these issues by efficiently managing screen activity.

Extinguish requires users to install Shizuku from Google Play Store or Github and follow its instructions to activate the necessary permissions. By doing so, users can unlock the full potential of Extinguish and optimize their device's power usage while preventing screen burn issues.
